%META:TOPICPARENT{name="OdsCalendar"}% ---+Manipulate my Calendar data via CRUD RESTful using Calendar CalDAV Endpoint %TOC% ---++What? Calendar CRUD (<b>C</b>reate, <b>R</b>ead, <b>U</b>pdate, <b>D</b>elete) Endpoint Service. ---++Why? Using CRUD RESTful Endpoint service provides an easy way to manage calendar tasks/events. ---++How? Knowing an Calendar CRUD Endpoint Service endpoint URL, one can perform the following activities: * Copy-paste vCard files containing calendar tasks/events. So once pasted, the system creates the calendar tasks/events; * Edit task(s)/event(s); * Update task(s)/event(s); * Delete task(s)/event(s); * Update RDF Data for the Calendar instance. Depending on the instance's model: * When model is "Closed", will be updated the RDF Data for the instance's private graph: <verbatim> http://cname/dataspace/protected/[name-of-the-instance] </verbatim> * When model is "Opened", will be updated the RDF Data for the ODS Dataspace public graph: <verbatim> http://cname/dataspace/[name-of-the-instance] </verbatim> ---+++Example with Calendar instance that has Member model from type "Closed" and is not set "Visible to public" 1. Suppose a user, for ex. "demo", has created Calendar instance with name "demoCalendar" and <code>Member model</code> is "Closed": %BR%%BR%<img src="%ATTACHURLPATH%/clcrud1.png" />%BR%%BR% 1 Mount the Calendar CalDAV Endpoint URL <code> http://localhost:8890/DAV/home/demo/calendars/demoCalendar/</code> %BR%%BR%<img src="%ATTACHURLPATH%/clcrud2.png" />%BR%%BR% %BR%%BR%<img src="%ATTACHURLPATH%/clcrud3.png" />%BR%%BR% %BR%%BR%<img src="%ATTACHURLPATH%/clcrud4.png" />%BR%%BR% 1 Drop a .vcf file, for ex. <a href="%ATTACHURLPATH%/demo-calendar.ics" style="wikiautogen">demo-calendar.ics</a> into the mapped CalDAV Calendar folder: %BR%%BR%<img src="%ATTACHURLPATH%/clcrud5.png" />%BR%%BR% 1 The user demo's Calendar Dataspace instance UI now should show under "Tasks"/"Events" the new imported task(s)/event(s): %BR%%BR%<img src="%ATTACHURLPATH%/clcrud6.png" />%BR%%BR% %BR%%BR%<img src="%ATTACHURLPATH%/clcrud7.png" />%BR%%BR% 1 [[http://ods.openlinksw.com/dataspace/dav/wiki/ODS/ODSGenerateX509Certificate][Generate an X.509 Certificate hosted WebID]] for user "demo" WebID. 1 [[http://virtuoso.openlinksw.com/dataspace/dav/wiki/Main/VirtAuthFOAFSSLACL][Secure your SPARQL Endpoint via user "demo" WebID]], for ex.: <verbatim> -- user "demo" WebID: http://localhost:8890/dataspace/person/demo#this -- SPARQL-WebID Endpoint: -- https://localhost:4433/sparql-webid </verbatim> 1 Access the SPARQL-WebID Endpoint. 1 When challenged for authentication select the generated from above certificate for user "demo": %BR%%BR%<img src="%ATTACHURLPATH%/abcrud8.png" />%BR%%BR% 1 The SPARQL-WebID Endpoint UI should be presented: %BR%%BR%<img src="%ATTACHURLPATH%/abcrud9.png" />%BR%%BR% 1 Enter the following query: <verbatim> SELECT * FROM <http://localhost:8890/dataspace/protected/demoCalendar> WHERE {?s ?p ?o} </verbatim> %BR%%BR%<img src="%ATTACHURLPATH%/clcrud10.png" />%BR%%BR% 1 As result no rows are found. ---+++Example with Calendar instance that has Member model from type "Opened" and is set "Visible to Public" 1.
